Anaerobic Digestion Modeling: from One to Several Bacterial Populations

TecnoLógicas, 2013
Anaerobic digestion systems are complex processes that unfortunately often suffer from instability causing digester failure. In order to be able to design, optimizing and operate efficiently anaerobic digestion systems, appropriate control strategies ...

Effects of Cellulase and Lactobacillus plantarum Supplementation on Fermentation Characteristics, In Situ Degradability, and Microbial Community Dynamics of Apple Pomace Silage

Animal Research and One Health, EarlyView.
This study aimed to investigate the effects of cellulase and Lactobacillus plantarum on the silage quality, in situ digestibility, and microbial communities of apple pomace silage. The combined supplementation of cellulase and Lactobacillus plantarum in apple pomace silage improved fermentation quality and enhanced rumen utilization efficiency.

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species

Animal Research and One Health, EarlyView.
A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome

Feedstocks influence on the process parameters and the microbial community in anaerobic digestion [PDF]

, 2013
To improve our understanding into the key parameters controlling and regulating the microbial groups involved in the anaerobic digestion (AD) process, particularly over multiple changes in operational conditions, triplicate lab-scale digesters fed with

Energy system model design and development for thermal hydrolysis process integrated with anaerobic digestion in municipal wastewater treatment plants

Results in Engineering
Anaerobic digestion is commonly employed for sludge stabilization in municipal wastewater treatment plants; however, its efficiency is hindered by the slow rate of sludge biodegradation.

Improvement of anaerobic digestion of sludge

Water Science and Technology, 2004
Anaerobic digestion improvement can be accomplished by different methods. Besides optimization of the process conditions, pretreatment of input sludge and increase of process temperature is frequently used. The thermophilic process brings a higher solids reduction and biogas production, a high resistance to foaming, no problems with odour, better ...

Effect of Cyclic Heat Exposure on the Growth Performance and Metabolism of Broilers Fed Palm Kernel Meal

Animal Research and One Health, EarlyView.
The aim of our study is to evaluate the interaction between HS and the incorporation of PKM in broiler chicken diets, as well as its effect on growth performance and metabolism. Based on the results obtained, PKM supplementation failed to mitigate the adverse effects of heat stress in broiler chickens. ABSTRACT The aim of this study was to evaluate the

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

Animal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and
